Rescale Pixel Factor to to something more manageable

The old scale between 30 and 10000 was not user friendly and it was inverted (bigger value got smaller stroke)

Now the default scale is 1.0 and bigger values get thickerr strokes.

Merge branch 'master' into blender2.8

Simplify & optimize code in BM_lnorspace_invalidate().

Quiet sure that one is correct, and it does not have to invalidate all
loops (smoothfans) of all faces of a given affected vertex, only
neighbor ones should be enough.

Also, no need to loop into smoothfans here, since we already check on
all loops of all vertices.

Depsgraph: Fix mistake in previous refactor commit

Fix broken initialization of normals when first editing them.

rBdd6642bb80ac fixed one case but broke a lot others (including when
custom normals data were already there before strating editing the mesh...).

Now simply using same (new) code from master when creating empty clnors
data, i.e. defining sharp edges as needed to mimic results from
autosmooth shading.
